Aurora blends heritage homes near the historic town core with newer subdivisions off Bayview and Wellington. Older basements often need waterproofing and egress upgrades first, while newer ones finish quickly into theatres, gyms and family space.
With strong demand for in-law suites and rental units across York Region, a properly finished Aurora basement is both lifestyle and investment. Whatever you start with, you end with finished square footage your family uses every week, and a number your Aurora house carries at resale.

Aurora requires a building permit before a basement is finished or converted into an additional residential unit, with staged inspections through construction. Under Ontario's updated housing rules, additional units are now permitted on most urban residential lots subject to the town's zoning. Older homes near the core often need egress and moisture work designed in from the start, something we confirm for your specific address before drawings are filed. Our licensed structural engineer prepares and stamps the drawings, and we pull the permit and manage every inspection to final sign-off.
